The Major Type and Mineralization Prediction of Molybdenum Deposits in China

Molybdenite is abundant in China and it distributed extensively in every province.The type and elements combination of Mo deposits are diverse.Based on extensive data collection and field investigation,this paper summarized the characteristics of molybdenum ore resources in China and divided Mo deposits in China into 4groups,12classes,19ore deposit-types in comprehensive consideration of ore deposit genesis,occurrence condition and ore-controlling factors,ore components,tectonic structure etc.And further we concluded ore body occurrence condition,hydrothermal alteration and mineralization assemblages of every type of Mo deposits.According to the analysis of tectonic,magma,etc,the prospecting potential of molybdenum in China is great.We analyzed porphyry Mo deposits′geological formation background of the continental orogenic environment in China and summarized various metallogenic characteristics of magmatic type Mo deposits.Through analysis on tectonic background,tectonic magmatic fluid events and element combination,we point out the arrangement of study and exploration:the first is magmatic-type Mo deposit and the second is fluid-type Mo deposit.The forecast of east Qinling,Yanliao and Tethys Mo metallogenic area demonstrates the focus of future prospecting work in those regions,which has important guiding significance in geological prospecting and studies on Mo deposits in China.
